Based on this, a kind of page data transmission method and system are the embodiment of the invention provides.Lead to below Embodiment is crossed to be described.
Embodiment 1
Referring to Figure 1A, a kind of page data transmission method is the embodiment of the invention provides.The method is specific Comprise the following steps：
Step 101：Server sets up one or more different super web page templates and saves it in it In itself and client, each super web page template is included in same under each path of a certain class website The non-figure web resource of class.
In embodiments of the present invention, server can be the corresponding background server of browser or agency's clothes Business device etc..
The data structure of above-mentioned super web page template includes non-figure web resource type, the website domain of website List of file names, the version number of super web page template and the content by above-mentioned non-figure web resource type in website The text data being merged into.Non- figure web resource includes the JavaScript scripts and CSS samples that outreach Formula table, above-mentioned non-figure web resource type includes script type and pattern class, and super web page template can be Script supertemplete and pattern supertemplete.
The use of super web page template is the website domain name based on website, because the non-figure of different web sites There is very big difference in the convergence situation and size of data of web resource.Super web page template is directed to website All similar non-figure web resource under each path, primarily directed to JavaScript scripts and CSS CSS, i.e., for the website domain name for giving, the corresponding super web page template of the website domain name is most There are a script supertemplete and one style supertemplete more.
In embodiments of the present invention, it is adaptable to the condition bag met needed for the website of super web page template Include：
(1) number of the similar non-figure web resource under each path in website is less than default value, and together The total capacity of the non-figure web resource of class is less than the similar non-figure web under each path in preset capacity, i.e. website Resource is to assemble and convergent, so avoids client and server from preserving and safeguard super web page template Overhead it is excessive；
(2) user's visit capacity of website belongs to the website of high frequency access higher than predetermined threshold value, i.e. website, The utilization rate of the corresponding super web page template of website that high frequency is accessed is very high；
(3) the correcting frequency of website is less than predeterminated frequency, and correcting frequency refers to that the script of website is used Technology or the framework frequency that great changes will take place, such as website is transferred to another from certain script bank Script bank, or website format layout occur Important Adjustment, then or website CSS files occur Very big change.Great changes will take place for the corresponding non-figure web resource possibility in website during due to website revision, So need to regenerate the corresponding super web page template in website after correcting, it is therefore desirable to which website changes Version frequency is less than predeterminated frequency, to avoid frequently generating the super web page template of redaction, reduces super The storage of web page template and maintenance cost.
In embodiments of the present invention, server determines that the completely the same multiple websites of organizational structure simultaneously should The website domain name composition website domain name list of multiple websites, determines non-under each path of this multiple website Figure web resource type, and set the version number of the super web page template.
Server can be according to the version number of the default release-naming rule settings super web page template.In advance If release-naming rule can be to be numbered according to natural number or lexicographic order.
The content of non-figure web resource type in website is merged into text data by server.Specifically, Server is based on file-level, and the content of the above-mentioned non-figure web resource type under each path in website is direct It is merged into text data；Or, server first determines the above-mentioned non-figure web resource under each path in website Similarity degree in the content of type between each data block, the non-figure web resource class under each path Data block of the similarity degree more than preset similarity value is extracted in the content of type, the data block that will be extracted is closed And into text data.
The text data that server is obtained by default AES and encryption algorithm to above-mentioned merging It is encrypted and encoding operation, obtains the identifier of the super web page template, while is made with the identifier It is the filename of the super web page template.
Above-mentioned identifier is to safeguard same super webpage mould as server and client identification both sides Plate and issue the crucial foundation of incremental data.
Above-mentioned default AES can be MD5 (Message-Digest Algorithm 5, letter Breath-digest algorithm 5), default encryption algorithm can be base64 (for transmitting 8Bit byte generations The coded system of code).Server is encrypted computing and obtains by MD5 algorithms to above-mentioned text data Ciphertext, obtains the character of the preceding predetermined number of the ciphertext, and the character for obtaining is carried out by base64 Transcoding computing obtains 8 characters, and this 8 characters are defined as the identifier of super web page template. Preceding 6 characters of ciphertext can be taken in the embodiment of the present invention 8 characters are encoded to by base64 Identifier.
Text data, the identifier of generation, the website domain name of composition that server obtains above-mentioned merging List, non-figure web resource type and version number constitute super web page template, by the super web page template Storage is in server and client side.
Client managed in the way of independently of client local cache its storage one or more surpass Level web page template.During client terminal start-up, super web page template is loaded, respectively with website domain name and mark Symbol sets up double indexes of super web page template, quick in order to slave site domain name and two dimensions of identifier Get corresponding super web page template.
Client is corresponding super to turn off or on a certain class website by the control parameter that backstage issues Level web page template.It is corresponding that server can also turn off or on a certain class website by control parameter Super web page template.
Due to the corresponding website of super web page template it may happen that correcting, in order to ensure super webpage mould The validity of plate, in a preferred embodiment of the invention, server needs periodically to detect net Stand whether correcting, if correcting, generation correcting after the corresponding redaction in website super web page template, And indicate client to update the super web page template of the redaction.
As shown in Figure 1B, the process for updating super web page template includes：
S1：Server detects the correcting of the corresponding website of each super web page template every preset time period Degree, when the correcting degree for detecting a website exceedes default correcting degree, according to correcting after should Website generates the super web page template of the corresponding redaction in the website；
Above-mentioned preset time period can be 5 hours or 10 hours etc..Stored for server local Each super web page template, server loads the corresponding website of super web page template every preset time period All non-figure web resource in domain name list under each website domain name, and each non-figure web resource Delta compression computing is carried out with the super web page template and obtain delta compression data, calculate each increment pressure The delta compression rate of contracting data, delta compression rate can embody the correcting degree of website.When certain website All non-figure web resource delta compression rate exceed compression ratio threshold value when, determine the correcting of the website Degree exceedes default correcting degree, then the non-figure web resource based on the website after correcting generates the net The super web page template of corresponding redaction of standing.
S2：The page request that server sends according to client, determines being accessed for client-cache The version of the corresponding super web page template in website whether be latest edition, if it is, to the page Request carries out response, if it is not, then performing step S3；
Website domain name and version number are parsed in the page request that server sends from client, according to this Website domain name obtains the version number of the corresponding super web page template of the website domain name from server local.If The version number of server local is higher than the version number in page request, it is determined that go out being somebody's turn to do for client-cache The corresponding super web page template of website domain name is not latest edition.
When server determine client-cache be not latest edition when, server this will issue page Request in person the partial data of the non-figure web resource required for asking.
S3：Server transport update instruction information gives the client；
Above-mentioned update instruction information include the identifier of the super web page template of legacy version and version number, The super web page template pair of the identifier of the super web page template of redaction and version number and redaction The website domain name list answered.
S4：The client is downloaded from server according to the update instruction information and stores the super webpage mould The latest edition of plate.
After client receives the update instruction information that server is issued, can update at once, it is also possible to On follow-up certain suitable opportunity, row updates again, such as updated again when being switched to WiFi network.
The idiographic flow that client updates super web page template is as follows：
1, the identifier of the super web page template of legacy version of the client in update instruction information, Mark the super web page template of legacy version invalid in super web page template manager；
2, client sends and updates request to server；
Renewal request carries the identifier and version number, redaction of the super web page template of legacy version The applicable website of the super web page template of the identifier of super web page template and version number and redaction Domain name list.
3, server receive client send the renewal request, compare the renewal request it is errorless after, Response is carried out to renewal request according to response protocol form：
After server confirms that the information write is errorless in renewal request, by certain compress mode to new The super web page template of version is compressed, and then encapsulates the super of redaction by response protocol form The identifier of web page template and version number, the corresponding website domain name row of the super web page template of redaction The super webpage of table, the compressed data of the super web page template of redaction, compress mode and redaction Data after encapsulation are transferred to client by template initial data size as reply data is updated.
4, client receives the renewal reply data, according to the renewal response of response protocol format analysis Data, after parsing the super web page template of redaction, judging the super web page template of the redaction is No successfully resolved, if success, performs step 6, if unsuccessful, performs step 5；

5, client re-flags the super web page template of legacy version in super web page template manager Effectively, record this renewal and mistake occur, the follow-up response based on server again indicates to be updated.
6, the super web page template of redaction is added to super web page template manager by client, and The super web page template of legacy version is deleted, this super web page template is completed and is updated.
In another preferred embodiment of the invention, can be provided with advance in server with client Client-cache strategy, the non-figure web money that client-cache policy definition client can be cached The condition met needed for source, the capacity of such as non-figure web resource can just be cached when being less than capacity threshold. Server judges according to the client-cache strategy first before non-figure web resource is issued to client Whether client can cache the non-figure web resource, if it is, indicating the client-cache non-figure web Resource, otherwise indicates client not cache the non-figure web resource.The client-cache plan for referring here to Any client-cache strategy well known in the art can be slightly used, excessive introduction is not done here.
When server determines that client can cache non-figure web resource, server is provided to the non-figure web The address in source and content carry out Hash operation and obtain a cryptographic Hash, using the cryptographic Hash as the non-figure web The mark of resource, and caching instruction, the non-figure web resource and its mark are handed down to client.Visitor Family end is slow by the non-figure web resource, the corresponding website domain name of the non-figure web resource and its mark correspondence In there is client local cache.
When user needs to browse the webpage of certain website and clicks on the corresponding link of the webpage, client will The corresponding website of the link is defined as the website that need to be accessed, and the net is obtained from client local cache The mark of the corresponding non-figure web resource of website domain name stood, the mark of the non-figure web resource that will be obtained Composition client-cache list, client obtains the mark of the corresponding super web page template of the website domain name Symbol, version number and Fei Tu web resource types.Client sends page request to server, in the page Request in person and ask middle carrying website domain name, client-cache list, identifier, version number and Fei Tu web Resource type.
Step 102：Server receives and parses through the page request of client transmission；
Server receives the page request that client sends, and parses client from the page request The website domain name of the website for being accessed, and parse client-cache list, identifier, version number With non-figure web resource type.Step 103：Required for being preserved in the local cache of client During non-figure web resource, server indicates client that institute is directly read from the local cache of the client The non-figure web resource for needing；
Server is obtained and the website domain according to the website domain name for parsing and non-figure web resource type Name it is corresponding and with the non-non- figure web resource of figure web resource type identical for parsing, to the non-figure The content of the corresponding address of web resource and the non-figure web resource carries out Hash operation, obtains the non-figure The corresponding cryptographic Hash of web resource, the cryptographic Hash is defined as the mark of the non-figure web resource.Calculate After going out the mark of the non-figure web resource, it is determined that whether comprising meter in the client-cache list for parsing The mark of calculation, if comprising the non-figure web required for being preserved in the local cache for judging client There is no the non-figure web resource required for preserving in the local cache of resource, otherwise client.
Server will cache configured information and be sent to the client, and this has cached configured information includes institute The mark of the non-figure web resource for needing and cashing indication.Client receives this and has cached configured information, The mark of non-figure web resource required for configured information includes has been cached according to this directly from client Required non-figure web resource is obtained in local cache.
Server can be according to preset protocol form the http response headers of the non-figure web resource and non- The mark of figure web resource and cashing indication has been packaged, client is handed down to by the information after encapsulation. After client receives the information that server is issued, solved from the information according to above-mentioned preset protocol form The http response headers of the non-figure web resource and the mark of non-figure web resource and cashing indication are separated out, And according to the mark of the non-figure web resource from client local cache the corresponding non-figure of direct access Web resource.Above-mentioned preset protocol form can be the standard agreement form of HTML5.
In a preferred embodiment of the invention, can be provided with advance between server and client side Client-cache strategy, when server needs to issue non-figure web resource to client, and the non-figure web When resource hits the client local cache, server need not issue the non-figure web resource, but Directly indicate client that the non-figure web resource is obtained from local cache, so need not again carry out it He operates, and also greatlys save transmission flow.
Step 104：When the non-figure web resource required for not having to preserve in the local cache of client, The non-figure web resource that server will be obtained according to page request carries out delta compression with super web page template Computing, obtains incremental data；
Server obtains right according to the website domain name of parsing from the corresponding Website server of the website domain name The non-figure web resource answered, and the identifier according to the super web page template for parsing and version number, from Corresponding super web page template is obtained in its one or more super web page template for preserving, according to acquisition Non- figure web resource and super web page template carry out delta compression computing, obtain incremental data.
In embodiments of the present invention, server can be by SDCH (Shared Dictionary Compression over HTTP, the mechanism of http data compressions is carried out based on dictionary) to non-figure web Resource and super web page template carry out delta compression computing.
SDCH is a kind of extension compatible with HTTP/1.1 (HTTP-version 1.1), It supports the compression to http response data by sharing dictionary between clients and servers. The scene of SDCH applications is as follows：Server first issues dictionary to client by the extension；Work as client When asking a certain http resources, the resource can be based on the same word that both sides preserve by server Allusion quotation carries out delta compression, and server issues incremental data to client；Client uses corresponding increment Incremental data is reduced to asked http resources by compression algorithm.
The super web page template stored in server and client side in the embodiment of the present invention is above-mentioned visitor The dictionary shared between family end and server.For the two number evidences for giving, using a data as word Another data is compressed by allusion quotation or template using delta compression algorithm, can be based on this two number Same data stream in is identified, so as to reduce the identical data in the compressed data of output Stream.This two number is higher according to similarity, then incremental data is fewer.Delta compression algorithm is also provided simultaneously Incremental data based on generation carries out itself compression of different stage to reduce the size of incremental data, Further improve compression effectiveness.
Because all pages under each path of some websites all use same super web page template, each page The variance data in face is considerably less, it is assumed that the similarity of each page is close to 90%, then by using SDCH Technology, server first issues the super web page template of the website to client, when client accesses the net During a certain page stood, the response page can be carried out based on super webpage mould using delta compression mode The incremental data of plate, the purpose of transmitting data stream amount is reduced so as to reach.
In another preferred embodiment of the invention, increment buffer service is provided with server, And the identifier of the mark of the non-figure web resource of delta compression computing, super web page template will have been carried out And delta compression operation result is buffered in server local caching system, the delta compression operation result is Success flag and incremental data, or the delta compression operation result are unsuccessfully to identify.
Success flag and unsuccessfully mark are what is determined by the delta compression rate of incremental data.Delta compression Rate is the ratio between the capacity and the capacity of non-figure web resource of incremental data.If the increasing of incremental data Amount compression ratio is less than default compression threshold, then in the delta compression fortune of server local caching system storage Calculating result includes success flag and the incremental data.If the delta compression rate of incremental data is more than or equal to The default compression threshold, the then delta compression operation result for being stored in server local caching system is only wrapped Include and unsuccessfully identify.The default compression threshold can be 5% etc..
Multiple transfers that above-mentioned increment buffer service can make to operate on server browse service processes The delta compression operation result of shared increment operation.Primarily with respect to a given non-figure web resource, Multiple users are there may be to be required for issuing the non-figure web resource, or same user is when different Between section need to issue the non-figure web resource, and the non-figure web resource and its super webpage mould of matching Plate is all changeless within limited a period of time, so by increment buffer service in server The increment of the local cache system cache non-increment operation of the figure web resource relative to super web page template Compaction algorithms result, can effectively reduce the delta compression computing to the non-figure web resource, so as to save Save the computing resource of processor.
Due to server there is provided increment buffer service, thus server carry out delta compression computing it Before, can first passing through increment buffer service inquiry server local caching system, whether to have cached this non- The corresponding delta compression operation result of mark of the mark of figure web resource and super web page template.Work as clothes During the business uncached corresponding delta compression operation result of device local cache system, server is again by the non-figure Web resource carries out delta compression computing with super web page template, obtains incremental data.When server sheet When ground caching system has cached corresponding delta compression operation result, directly system is cached from server local System obtains corresponding delta compression operation result, and subsequent server is according to the delta compression operation result pair Page request carries out response.
In embodiments of the present invention, when the uncached corresponding delta compression fortune of server local caching system Calculating result and server is carried out after delta compression computing obtains incremental data, and server calculates the incremental number According to capacity and the capacity of non-figure web resource between ratio, obtain the non-figure web resource corresponding Delta compression rate.If the delta compression rate is less than default compression threshold, server is cached by increment Service is by the mark of the non-figure web resource, the identifier of the super web page template, success flag and is somebody's turn to do Incremental data is cached to server local caching system.If the delta compression rate is more than or equal to default pressure Contracting threshold value, then server by increment buffer service by the mark of the non-figure web resource, the super net Page template identifier and unsuccessfully mark be cached to server local caching system.
Step 105：Incremental data is transferred to client by server.
When the uncached corresponding delta compression operation result of server local caching system and server enters After row delta compression computing obtains incremental data, if the delta compression rate of the incremental data is more than default pressure Contracting threshold value, then carry out response with incremental mode to the page request of client.Otherwise, with partial data Mode carries out response to the page request of client.
When server local caching system has cached corresponding delta compression operation result and the increment pressure When contracting operation result includes success flag and incremental data, server is entered with incremental mode to page request Row response.When server local caching system has cached corresponding delta compression operation result and the increment When compaction algorithms result includes unsuccessfully identifying, server is answered page request in partial data mode Answer.
In a preferred embodiment of the invention, can be provided with advance between server and client side Client-cache strategy, before server carries out response to the page request of client, according to server The existing client-cache strategy between client, the non-figure web moneys required for judging page request Source generates client-cache and judges mark if appropriate in client local cache according to judged result Know.
It is above-mentioned response is carried out with incremental mode operation be：Server is non-to this by preset protocol form The page response header of figure web resource, client-cache judge mark, increment operation mark, surpass The level identifier of web page template, the original size of the non-figure web resource, the size of incremental data and increasing Amount data are packaged, and client is transferred to using the data after encapsulation as page reply data.
The page reply data of client the reception server transmission, by the preset protocol format analysis page Face reply data, according to the identifier that page reply data includes, obtains from client local cache Corresponding super web page template is taken, the incremental data in the web page template and page reply data is also Original goes out required non-figure web resource.
In embodiments of the present invention, size and the page of the client always according to the non-figure web resource of reduction The original size that reply data includes judges whether restoring operation succeeds, if the non-figure web resource of reduction Size it is consistent with original size, then reduce successfully, otherwise go back primary failure.Also primary failure shows data Transmission goes wrong, and abandons the non-figure web resource that reduction is obtained.
If reducing the client-cache successfully and in page reply data judges that mark instruction needs caching, To be buffered in client local for the non-figure web resource that then client will be reduced.
It is above-mentioned response is carried out in partial data mode operation be：Server is by presetting compress mode pair The non-figure web resource is compressed, and obtains compressed data, by preset protocol form to the non-figure web The page response header of resource, client-cache judge mark, the mark and pressure of default compress mode Contracting data are packaged, and client is transferred to using the data after encapsulation as page reply data.It is above-mentioned Default compress mode can be gzip or 7zip etc..
The page reply data of client the reception server transmission, by the preset protocol format analysis page Face reply data, the mark of the default compress mode in page reply data, using corresponding pre- If compress mode is decompressed to compressed data, required non-figure web resource is obtained.If client End caching judges that mark instruction needs caching, then required non-figure web resource is buffered in into client Locally.
The preset protocol form and response protocol form being previously mentioned in the embodiment of the present invention can be HTML5, WebApp agreement or H264 agreements etc..The embodiment of the present invention in above-mentioned each threshold value all Can be set based on empirical value.
The beneficial effect of the embodiment of the present invention is：Set up one or more different super web page templates and incite somebody to action It is stored in server and client side, and super web page template is including similar under a certain each path in class website Non- figure web resource.When required non-figure web resource is not existed in client local cache, The non-figure web resource that server will be obtained according to page request carries out delta compression with super web page template Computing obtains incremental data, and incremental data is transmitted into client.Because server is only by non-figure web moneys Incremental data between source and super web page template is transmitted to client, it is to avoid issue non-figure web resource Partial data, shorten the page response time, save transmission flow.
